This series of hermetic-packaged, high-power MOSFETs is specially designed for linear applications. Rated at 525W, total power dissipation 500V and 1000V, these parts have an extended forward biased safe operating area (FBSOA). The package provides protection for harsh environments and military applications and is available with and without MIL-PRF-19500 screening. Linear applications, like electronic loads, using constant operation in the linear region require high dissipation and FBSOA.

Low Noise LDO
The NCP500 is a CMOS low noise LDO voltage regulator featuring low dropout voltage and a five-lead SOT-23 package. It provides space and cost savings ideal for applications requiring low noise operation, fast enable response times, and low dropout. It's optimized for use in cellular handsets, achieving its low noise performance without an external noise bypass capacitor. Operating within a voltage range of 1.8V to 6V, it has an enable pin and current and temperature limit protection circuits.

Bipolar Power Transistor
This family of high-gain bipolar power transistors features low saturation voltage, making the transistors suited for low-voltage switching applications. Typical uses for the STT818A/B transistors include power management in portable equipment and switching regulators in battery chargers. The high-gain PNP power transistor has an inter-digitated layout, exhibiting a typical collector-emitter saturation voltage of 0.25V (for IC=2A and IB=20mA). They have a minimum dc current gain of 100 and a value of 200.
Thermal Gap Fillers
The T-flex 600™ Series of highly compressible gap fillers alleviates tolerance problems incurred when multi-chip components are mated to a universal heat-spreading device. This ultra-soft interface pad conforms with minimal pressure, resulting in little or no stress on the mating parts. It has a high thermal conductivity of 3W/m°C and low thermal resistance. It's compressible at 16% at 5 psi (for 40 mil material), and 46% at 50 psi (for 40 mil material). Material recovery (more than 90%), and a naturally tacky surface makes it reusable and easy to rework.
